Problem connecting to a Blue Host domain

I am a graphic designer relatively new to webflow and I am trying to publish a portfolio website for a client ( to a BlueHost Domain that a 3rd party has under a main domain (as part of a domain hosting service she does for her client). The errors have ranged from too many reroutes to someone is trying to hack your information to 404 message. I am showing it as connected on my side with a green light.

I sent her the correct CNAME and 2 @ files to add and she said she has done that and also spent considerable amounts of time on with Blue Host Customer Service so I am wondering if there is something on my end that is wrong?
